Answer:

The circumference of a circle is the distance around the outside of the circle

Hope It Helps :)

Step-by-step explanation:

Answer:

Circumference of the circle or perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of circle defines the region occupied by it. If we open a circle and make a straight line out of it, then its length is the circumference. It is usually measured in units, such as cm or unit m.

When we use the formula to calculate the circumference of the circle, then the radius of the circle is taken into account. Hence, we need to know the value of the radius or the diameter to evaluate the perimeter of the circle.

Circumference of a Circle Formula

The Circumference (or) perimeter of a circle = 2πR

where,

R is the radius of the circle

π is the mathematical constant with an approximate (up to two decimal points) value of 3.14

Again,

Pi (π) is a special mathematical constant; it is the ratio of circumference to diameter of any circle.

where C = π D

C is the circumference of the circle

D is the diameter of the circle

For example: If the radius of the circle is 4cm then find its circumference.

Given: Radius = 4cm

Circumference = 2πr

= 2 x 3.14 x 4

= 25.12 cm

Answer:

The value of the test statistic and its associated p-value at the 5% significance level are -1.54 and 0.9382, respectively.

Step-by-step explanation:

A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.16.

This means that the null hypothesis is:

[tex]H_{0}: p \geq 0.16[/tex]

Testing this hypothesis, means that the alternate hypothesis is:

[tex]H_{a}: p > 0.16[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.16 is tested at the null hypothesis:

This means that [tex]\mu = 0.16, \sigma = \sqrt{0.16*0.84}[/tex]

In a sample of 200 graduates, 24 students have a GPA of 3.00 or below.

This means that [tex]n = 200, X = \frac{24}{200} = 0.12[/tex]

Value of the test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.12 - 0.16}{\frac{\sqrt{0.16*0.84}}{\sqrt{200}}}[/tex]

[tex]z = -1.54[/tex]

Pvalue:

The pvalue is the probability of finding a sample mean above 0.12, which is 1 subtracted by the pvalue of z = -1.54.

Looking at the z-table, z = -1.54 has a pvalue of 0.0618

1 - 0.0618 = 0.9382

The value of the test statistic and its associated p-value at the 5% significance level are -1.54 and 0.9382, respectively.

Answer:

[tex]y=\frac{1}{13} x+\frac{32}{13}.[/tex]

Step-by-step explanation:

1. the midpoint of the side AC is:

[tex]D:(\frac{3-2}{2};\frac{4+1}{2})=(0.5;2.5).[/tex]

2. if the coordinates of the points B and D are (7;3) and (0.5;2.5) respectively, then it is possible to make up the required equation of the median BD:

[tex]\frac{x-7}{7-0.5}=\frac{y-3}{3-2.5}; \ \frac{x-7}{13}=\frac{y-3}{1}[/tex]

or

[tex]y=\frac{1}{13} x+\frac{32}{13}[/tex]

Answer:

AB = 7.10

Step-by-step explanation:

Reference angle = 65°

Hypotenuse = AB = ?

Adjacent side length = BC = 3

Apply the trigonometric ratio CAH, to find AB.

Cos 65 = Adj/Hyp

Cos 65 = 3/AB

AB*Cos 65 = 3

AB = 3/Cos 65

AB = 7.09860475

AB = 7.10 (nearest hundredth)

Answer:

  A, D

Step-by-step explanation:

The figure looks symmetrical, but their is no given information indicating it actually is symmetrical. Thus we can't make any statements about the segment lengths. Nor is there any indication that any of the arc lengths are identical.

If we rule out statements about segments and arcs, that only leaves statements about angles. As it happens both of those are true: inscribed angles that intercept the same arc are congruent.

The true statements are ...

  A: ∠CAD≅∠CBD

  D: ∠ACB≅∠ADB

Answer:

1= 240. 2= 1800

girl I suck at this but basically I just multiplied the base and the width then i multiplied the height bye the product of the base and width!

Please Dont Get Mad If Its Wrong.

Answer: I could be wrong but it's probably 3.

Step-by-step explanation: Once there's x in the 3 sides of angles you subtract. 73 minus 3 = 3 degrees. If I'm wrong sorry about that. I will try to improve. :)

Answer:

10

Step-by-step explanation:

Let's find f(2) first.

f(2) = 2 + 2 = 4

This means it would be f(g(4)).

Then let's find g(4).

g(4) = 4 + 4 = 8

Then, this means f(8).

f(8) = 8 + 2 = 10

Answer:

142 square meters

Step-by-step explanation:

     Big rectangle    Area =  LxW  =      18 x9= 162

White triangle  Area   A =   (ab)/2      legs 5 and 8   ( 18-10= 8 )

= (5x8)/ 2  = 20

Subtract white triangle from green  rectangle

 162-20 = 142

    OR

area  left  rectangle    LxW     10x9 = 90

area  right rectangle    LxW       4x8 =32

area green triangle ( sides 5 an8 )   (ab)/2  =   20

90+32+20 =  142

Answer: x = 12

Step-by-step explanation:

subtract 8 on both sides (12-8=4)

now we have 1/3x = 4

multiply 3 on both sides (4 x 3 = 12)

now we have x = 12

Answer:

see explanation

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 16 ← is the equation of a circle

centre (0, 0 ) and r = [tex]\sqrt{16}[/tex] = 4

The circle therefore intercepts the x- axis at (4, 0 ) and (4, 0 )

and intercepts the y- axis at (0, - 4 ) and (0, 4 )

Domain is - 4 ≤ x ≤ 4

range is - 4 ≤ y ≤ 4

x- intercepts are x = - 4, x = 4

y- intercepts are - 4, 4

Answer:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 16 ← is the equation of a circle

centre (0, 0 ) and r = \sqrt{16}16 = 4

The circle therefore intercepts the x- axis at (4, 0 ) and (4, 0 )

and intercepts the y- axis at (0, - 4 ) and (0, 4 )

Answer:

0

Step-by-step explanation:

Answer: The piano has 222 strings, because 37×6=222.

Step-by-step explanation:

Since we are informed that Leslie tuned a guitar with 6 strings today and that she then tuned a piano with 37 times as many strings.

This simply means that we have to multiply 37 by 6 strings to get the value of the strings of the piano that she tuned. This will be:

= 6 × 37

= 222 strings.

Leslie tuned 222 strings.

Therefore, the piano has 222 strings, because 37×6=222.

Answer:

Jose will have played the guitar for 9.1 hours during those 6 days.

Step-by-step explanation:

Given that this week Jose played guitar for 3/4 of an hour on Tuesday, an hour and a half on Thursday, and 2.3 hours on Saturday, to determine, if Jose plays guitar for the same amount of time next week, how many hours will he have practiced over these 6 days, the following calculation must be performed:

3/4 = 0.75

1/2 = 0.5

(0.75 + 1.5 + 2.3) x 2 = X

4.55 x 2 = X

9.10 = X

Therefore, Jose will have played the guitar for 9.1 hours during those 6 days.

Answer:

0.3504 = 35.04% probability that a worthy proposal is disapproved by both panels

Step-by-step explanation:

We have that:

0.27 = 27% of the time, the proposal is judged worthy of funding by the first panel. So 100 - 27 = 73% probability of being disapproved.

52% of the time, the independent panel reverses the decision. So if the first panel disapproves the funding, 52% probability the second approves the funding and 100 - 52 = 48% probability it does not.

What is the probability that a worthy proposal is disapproved by both panels?

48% of 73%. So

0.48*0.73 = 0.3504

0.3504 = 35.04% probability that a worthy proposal is disapproved by both panels
